and third speeds, respectively. and especially Figs. 1 to 6, the preferred form 01' Another object of the invention is to provide my invention which has been chosen to illustrate external locking means for all the car doors the principle thereof and its application is shown utilizing, in part, the mechanism employed for' applied to a common chassis frame i5, having the lock n the car doors as referred to above when usual channel sides it. Mounted on the top or I6 is a sill |1 supporting the usual body I8 provided with hinged doors I 9. The car in the form shown is what is called a four-door sedan type with the two doors on each side opening away from the center post. It will be understood, however, from the foregoing that my invention is applicable to two-door cars as well as cars having more doors. Referring particularly to Fig. 2, the car is provided with the usual running boards 20, secured to the channel sides l6. There is also provided the usual side plates 2| secured to the running boards and the body l3, and a supplemental casting 22 provided with a lower flange 23 and a pair of upper flanges 24, which castings 22 are secured by bolts to the channel sides l6. Mounted on each side of the car between the side plates 2| and the castings 22 are a pair of lock pins 25 so arranged as to reciprocate vertically in apertures in the flanges 24. Each pair of pins 25 is in the form shown integral with a horizontal plate 26 which is shown in the lowermost position in Fig. 5. Each horizontal plate 26 in. its lowermost position rests upon a pair of blocks 21 which limit the downward movement of the horizontal plates 26. A compression spring 28 encircles each lock pin 25 and isinterposed between the plate 26 and the flange 24 and these springs function to normally retain the plates 26 and lock. pins 25 in lowermost position. The threshold 29 of each side plate 2|, as particularly shown in Figs. 2, 4, and 5, has a slot 36 and the bottom flange 3|, of the casing of each door has a slot 32. A cam arm 33 is fixed on each end of a shaft 34 by means of a hub and pins, which shaft is mounted in bearings 35 suppported on the chassis members l6. At its outer end cam arm 33 has a ball bearing cam roller 3311. As will hereinafter more fully appear, the cam functions on the turning of the shaft 34 to raise 'or lower the plates 26 and the pins 25 upwardly into the slots 30 and 32 thus locking the doors, the pins being depressed out of the slots by means of the springs 28 heretofore mentioned unlocking the doors when the shaft 34 is turned back to its original position. It will also be seen that the supplemental casting 22 and its flanges provided with apertures act to guide the vertical reciprocation of the pins 25.

A shaft 34 is provided with a rock arm 36 (Figs. 2 and'l) to which is pivotally connected a connecting link 31 which has an elongated slot 38 at its free end in which a pin 39 is free to reciprocate under the action of an armature 40, to which pin 39 is connected. Armature 40 is actuated by solenoid 4|, which, in turn, is suitably mounted on a bracket 42 secured to side channel member I6 or otherwise, if desired. The motor vehicle has the usual engine 43, transmission 44, and gear shift lever 45, the latter being connected to the usual shifter fork rods, one of which is shown at 46, preferably being the one used to shift the gears from the intermediate or second speed position to the third or high speed position. Shifter rod 44 has integrally secured to it a rod extension member 41 which is somewhat Z-shaped in plan view, as shown in Fig. 7a, and has a cam surface 48 and a cam surface 49, these cam surfaces being separatedby recess opposite which in the neutral position of the lever 45 is a push button 5| of a switch 52 suitably mounted on a bracket 53 which, in turn, is Secured to the casing of the transmission 44. As the gear shift lever '45 is shifted from neutral to second speed position,

shifter fork rod 46 and extension member 41 will be shifted rearwardly of the car and. cam surface 2,182,767 each of the upper flanges of the channel members 48 will engage push button 5| closing the push button contact and similarly when the gear shift lever is shifted to the third or high speed position, shifter fork rod 46 and extension member 41 will be shifted forwardly with respect to the car and cam surface 49 will engage push button 5|, similarly closing the circuit through switch 52 as will be more fully apparent hereinafter.

The motor vehicle is shown having a usual electric generator 54 suitably mounted as at the side of the engine, the generator being driven by an auxiliary shaft 55, which may supply power for a water pump 56. The generator is provided with the usual cut-out relay 51 which has a generator contact 58 and a battery contact 59, which contact is connected by wire 66 through the usual ammeter A to the usual battery 6|. The generator is supplied with the usual generator contact 62 and is connected by generator contact wire 63 to the cut-out relay generator contact 58. A wire 64 connects wire 63 to one contact of button switch 52 and the other contact of switch 52 is connected by a wire 65 to one contact of solenoid 4|, the other contact of the solenoid having a ground wire connection 66, it being understood that one side of the battery 6| is also grounded in the usual manner. The operation of my invention as described hereinabove is as follows:

Assuming thev motor vehicle is at rest with the motor shut off and the gear shift lever 45 in neutral position, the door locking mechanism will be as shown in Fig. 5, with the cam arm 33 out of engagement with plate 26. When the engine is started and brought up to normal operating speed, the generator will create a voltage at contact 62 which will be supplied through wires 63 and 64 to push button switch 52. When the car has been put into motion, and gear shift lever 45 shifted to second speed position, the cam surface 48, will, as described above. engage push button 5|, which will close the contacts of switch 52 f and the generator voltage circuit will be completed through wires 65, solenoid 4| and ground wire 66. This will energize the solenoid, the armature 40 of which will be retracted, the pin 39 of the armature 40 engaging an outer end of slot 33 of link 31, shifting the link 31 forwardly, which motion will be transmitted through rock arm 36, rock shaft 34, which motion.will rock cam arm 33 to the position shown in Fig. 4, thus elevating the plates 26 and pins 25 in passing through slots 30 and 32 of the threshold 29 and clamp 3| of the casing, thus looking all of the doors of the vehicle. when the car is brought to a stop, and the gear shift lever returned to neutral, the contacts .of the push button switch 52 will be opened, breaking the circuit through the solenoid 4|, which will release the armature, and the cam arm 33 will be'returned to the position shown in Fig. 5 and the pins 25 retracted from the slots 36 and 32 by the action of springs 28. In stopping the car, if the gear shift lever is inadvertently or otherwise left in running or high speed position or the second or intermediate position, or the en gine stopped by the operation of the ignition switch, or in any other manner, the generator voltage willfall to zero, which will similarly deof a car being involved in an accident; assuming the driver and other occupants become disabled, and the stopping of the engine which would usually occur under such circumstances, the doors of the vehicle will be automatically unlocked.

The locking feature as described is of particular value when the motor vehicle is brought to a stop by highway conditions, such as stop signs or stop lights, it being possible to keep the doors locked against the incursion of an uninvited and unwanted person, this being possible by the gear shift lever being shifted to the intermediate or second speed upon arriving at the stop light or a stop sign, the car being maintained at rest by the release of the clutch pedal in thewell understood manner.

Referring now more particularly to Figs. 8 to 15, inclusive, the foregoing described results may be obtained in a mechanical manner. A similar motor vehicle engine and transmission being shown, a rock shaft 34 and rock arm 36 being connected by link arm 31a which is provided with a yoke 311), the arms of the yoke each having an elongated slot 38a which slot is similar to the slot 38 of the embodiment as shown in Figs. 1 to 7, inclusive, except that it is somewhat longer than slot 38 for a purpose to be hereinafter explained. A stub shaft 61 is reciprocable across slots 38a, and a rock arm 68 is secured to-shaft 61 at one end thereof and is pivoted at 68a to an elongated link member 69 one end of which is provided with a supporting bracket 18 suitably secured to side channel I6 or otherwise similarly mounted. At its forward end link 69 is pivotally connected to a bell crank 1| which is pivoted on a bracket 12 attached in any convenient manner to the engine or the car frame. Crank 1| is also pivoted to a link 13, which, in turn, is connected to the free end of a rock arm 14, (Figs. 9 and 10) arm 14 being connected to a stub shaft 15 mounted in a bearing bracket 16 suitably affixed to the engine 83. Shaft 15 also has secured to it a pair of yoke arms 11, the outer ends of which are provided with bearing rollers 18 positioned in a groove 19 of a thrust collar 88 which is freely 05- cillatable on the auxiliary shaft 55. Collar 88 is provided with a thrust plate 8I adjacent a bell housing 82 which is keyed to and rotatable with shaft 55. A plurality of pivots 83, are each pivoted to a bell crank 84 carrying a centrifugal weight arm 85 and a lever arm 86 which engages the far side face of thrust plate 8i. The spring 81' normallymaintains thrust collar 88 to the left, the collar being drawn to the right on the shaft 55 against the action of spring 81 by the action of weight arms 85, being thrown outwardly upon the rotation of housing 82 with the normal running of the engine 43. The operation of the foregoing described parts is such that when the engine is started the weight arms 85 will be thrown outwardly, moving thrust collar 88 to the right, which, in turn, will rock yoke arms 11 and rock arm 14 which will lift link 13 and cause link 69 to be shifted forwardly which will shift pivot 68:: from the position shown in Fig. 12 to that shown in Fig. 11. A second rock arm 88 is mounted on stub shaft 61 and has a pivot 88a to which'is connected one end of link 89, the other end being connected to a yoke arm 98, which is mounted in a pair of brackets 92 and 93 suitably secured to thetransmission 44. at one end, to shaft 9I and pivoted at the other end to a link 95, which, in turn, is provided with a pair of yoke arms 96 each of which has a narrow slot 91 which merges with an enlarged slot A yoke arm is secured,

98, the upper edges of the slots 91 comprising bearing shoulders 99 for the arms of a T-shaped rock member I88 pivotally mounted on a stub shaft I8I, which, in turn, is suitably mounted on bracket 93. Rockmember I88 has a pair of horizontally extending arms I82 and I83 and an upwardly extending actuating arm I84, the outer end of which is provided with a slot I85. A roller I86 is maintained in slot I85 and is pivoted on the outer end of a shifter rod extension member I81 which is integrally connected to shifter yoke rod 46. Shifter rod I81 corresponds in function to extension rod member 41 of the above deyoke arms 96 of the mechanism described. The operation of the mechanism described immediately preceding is as follows:

When the gear shift lever 45 is shifted forward to the intermediate or second speed position, shifter fork rod 46 is shifted rearwardly carrying with it rod extension I81, whichaction rotates rock member I88 counter-clockwise, as seen in Fig. 15, causing the elevation of arm I83, the-upper edge of which bearing on the adjacent shoulder 99 of one of the yokearms 96, causes link 95 to be raised, thus rotating yoke arm 94, thereby rocking shaft 9| and causing yoke arm 98 tobe rotated and drawing link 89 and pivot 88a forward to the position shown in 'full lines in Fig. 12. A comparison of Figs. 11 and 12 shows that the forward actuation of either link 69 or link 89 from the neutral or unlocked position with respect to the position of the .door lock pins 25 and the arm 31a is such that the shaft 61 will be shifted from its approximate mid-position in slot 38 to the right end of said slot and that no resulting action will occur with respect to arm 31a and the door lock mechanism connected with pins 25. Assume that the motor vehicle is put into operation in the usual and ordinary manner with the gear shift lever in neutral position and the engine started. As soon as the engine has acquired the usual idlingspeed, the link 69 would have been shifted forwardly as described hereinabove, carrying stub shaft 61 Fig. 11. When the motor vehicle has been put into forward motion and gear shift lever 45 shifted to second or intermediate speed position link 89 will be shifted forwardly carrying pivot.

88a forwardly, thus shifting arm 31a forwardly inasmuch as the shaft 61 has during this latter movement been in engagement with the forward end of slot 38a' causing the shift as described. This will result in the shaft 34 being rocked causing the cam arm 33 to raise the locking pins 25 to the locking position of Fig. 4 thus locking the doors of the motor vehicle.

W hen the gear shift lever 45 is shifted from the said intermediate or second position to the third or high position the shifter fork rod 46 will be shifted forwardly carrying the extension rod 41 through the neutral position and rock member I88 will be rotated clockwise and the arm I82 will now engage the opposite yoke arm 96, again causing the link 95 to be raised and the doors maintained in locked position as described.

forwardly in slot 38a to the position shown in 7 ing the door lock pins 25 to be withdrawn thus unlocking the doors. A similar result would have occurred if the engine had been stopped prior to shifting the gear shift lever to neutral position. In that case the link 68 would first have been returned to the normalor inoperative position,

as shown by the full line position of Fig. 12,

similarly releasing arm 81a and the door lock pins 25. As shown in Figs. 11 and 12, rock arms 88 and 88 being fixed to shaft 61, the two arms can be considered as branches of a single lever which may assume the positions shown, depending upon the sequence of operation of the gear shift lever and the engine. With the engine stopped and the gear shift lever in neutral, the arms 68 and 88 will assume the dotted position designated X in Figs. 11 and 12, the full line or Y position of Fig. 11 being that in which the link 69 has been actuated first, the position Y of Fig. 12 being that in which the link 89 has been actuated first, and the broken line or Z-position showing the position of the rock arm members 68 and 88 when both the links 88 and 89 have been actuated into operative position. From the foregoing it will be apparent that the doors will be locked only when the two conditions exist simultaneously, that is, the running of the engine and the position of the gear shift lever 45 in either the second or third speed position. This corresponds exactly with the result obtained with respect to the electrical operation hereinabove described.

As a further feature of my invention, I have provided means for locking the doors of the motor vehicle from the outside thereof, as when parking or otherwise leaving the vehicle unattended and these means utilize in part the mechanism described hereinabove.

A second rock arm III! is secured to shaft M and is pivotally connected to a link III, the forward end of which is pivoted to a rock arm H2 secured to a rock shaft H3 mounted in bearings H4 suitably securedto side channel members I8 and to the right hand running board 28, the bearings H4 and the rock shaft H3 being positioned somewhat forwardly of the right front door. A pedal I I5 attached to rock shaft III is suitably secured thereto and is provided with a foot plate H6 and a guard or kick plate H'I (Fig. 3). v A recess H8 is provided in the running board 28 for the foot plate H8 in such a manner that the plate H6 may be flush with the surface of the running board 20 when the pedal is in a depressed position. A rock arm H9 is secured to shaft H3 and is pivoted to a lock link I20, the upper end of which is contained in a lock housing I2I mounted inside the side panel of the motor vehicle between the forward edge of the front door and the hood of the engine. Suitable guides I22 are provided in the lock housing I2I for link I20, and the upper end of link I28 has a keeper slot I23 through which the lock bolt I24 of the lock is adapted .to enter to lock the link I20 when said link is in its upper position. The lock has the usual lock arm I25 by which the lock bolt I24 is thrown and has the usual key cylinder I26 and key slot I21. A spring I28 is secured at one end to link III and by the other end to shaft 24 and aids in normally maintaining the locking mechanism in unlocked position, aiding springs 28 in this function. In order to lock the doors from the outside, pedal I I5 is depressed which rocks shaft I I I3 shifting link III forward and lock link I28 upwardly. Link III and rock arm III! by rotating shaft 34, in a manner similar to that under the actuation of arms 31 and 31a, cause the pins 25 to lock the doors and at the same time, the key cylinder I26 may be operated by the key to cause arm I25 to throw the lock bolt I24 into engagement with the keeper slot I23 which is now in juxtaposition therewith. In this manner all of the doors of the car will be locked simultaneously and there will be no danger of leaving one or more of the doors unlocked, which is otherwise apt to occur with cars in which the doors are locked independently from within.
